This invention is an improvement in racks or hangers for articles to beelectro-plated,

- and more particularly in a rack or hanger for supporting plate-likearticles, in such manner as to leave substantially the entire surfacethereof exposed, and with a good electrical contact between the rack andthe ar- In order to obtain a smooth and even deposit on plate-likearticles, it is essential that the surface of the article be exposed to.the deposit throughout the entire area, while at the same timeelectrical contact must be maintainedbetween' the article and the rack.v

- One of theprimary objects of the present invention is the provision ofa rack or hanger especially designed for supporting articles of thischaracter, withsubstantially the entire surface thereof exposed, andwithclose contact between the article and the rack or hanger.

Another object is the provision of a rack havin members, resilient andlaterally displacea le to facilitate the insertion of an article, and soarranged that the insertlon of each article braces the resilient memberof the preceding article against lateral displacement.

Another object is the rovision of a rack wherein the resilient anlaterally displaceable members act to cause the angers to tightly engagethe articles when they are in place-in the rack. r With these and otherob ects 1n view the invention consists in the construction and novelcombination of parts. fully described hereinafter, illustrated in theaccompanying drawings and pointed out in the claims appended hereto, itbeing understood that various changes in the form, proportion, size andminor details of construction within the scope of the claims, may beresorted to without departing fromthe spirit of the inven- .tion.

In the drawings forming a part hereof Fig. 1 is a transverse verticalsection of a plating tank provided with the improved hanger;

Fig. 2 is a detail '1l 1 perspective of a part to-oftherack.

"The present embodiment of the inventionis shown in connection with aplating tank 1 of usual construction, having the usual cross bars 2,extending transversely or longitudinally of the tank, from which theracks or hangers are suspended, the'cross bars resting on the tops ofopposite walls of the tank, and being the circuit.

The improved rack includes a substantially U-shaped frame composed of abottom memher 3 and side members 4 extending upwardly from the bottommember, and each provided at its upper end with a hook 5 for. engaging across bar 2.v The side members 4 are connected atsuitable intervals by.cross bars 6 o f relatively small cross section, and of res1l1entmaterial. The cross bars are riveted or otherwise secured to the sidemembers 4, as indicated at 7, and each cross bar 6 .and the bottommember 3 carries a set of hangers for engaging the articles indicated ata, to be plated.

Each of the hangers is of substantially U-shape, comprising a body 8,which is soldered or otherwise secured to a cross bar 6, as indicated at9, and arms 10, extending from the ends of the body. The arms extendfrom the body at' an obtuse angle, as shown, and each is provided at itsouter end with an angular portion 11, which is notched as indicated at12 for ascribed. I

The angular portions 11 are substantially perpendicular to the crossbars 6, and to the bottom bar 3 of the frame. Referring purpose to bede- 'to Fig. 1, it will be seen that the hangers of the bottom member 3of the frame are opposed bya set on a cross bar 6, and a set on the oposite side of this crossbar 6,are opposed y a set on another cross bar.

connected to the negative lead of The bottom member 3 of the frame issub I stantially rigid, but the cross bar justv above it 1s resilientlydisplaceable away from the member 3 to enable insertion of an article.

The second cross bar from the member 3 is also displaceable in the samemanner, but

when an article has been placed between the lowest cross bar 6 and thenext lowest it braces the lowest cross bar against lateral displacement,so that'the article between the lowest cross bar and the member 3 istightly I I clamped by the hangers.

In use, a plate is first inserted between the bottom member 3 and theadjacent bar 6, the said bar 6 bein sprung upward inter-.

mediate its ends to. acilitate the insertion ofthe plate, and theplate-is held by its edges in the notches 12. Another plate is now in-jserted between the, lowermost bar 6 and the next 11 per in the samemanner, the next:

upper ar being-sprung to enable the insertlon of the plate.

It will be apparent that, the insertion of the second plate locks thefirst plate in place, acting as a brace to prevent springing of thelowermost bar 6. Practically the whole surface of the articleis exposedto the electroe plating action, while at the same time good electricalconnection is provided between the article and the rack,- to which thenegative lead isconnected. The tank is provided with 4 the usualanodesto which the is connected.

positive lead It will beapparent that the members 8- l0-11, which engagethe articles, contact with the articles only at the corners of the edgesThis is due-to the -V-shapeof the notches 12. The articles are slidahlelongi tudinally i'n'the members 810-'-11, so that" if desired, they maybe shifted longitudinally toexposethose minute portions which have beenengaged by the said members. 7
